Suicide and homicide rates: their relationship to latitude and longitude and to the weather.

The variation of suicide and homicide rates in the major standard metropolitan statistical areas of the United States was explored to see whether regional variations in temperature and precipitation could account for some of the variation. Controls for temperature eliminated the North-South variation in suicide rates, but not the North-South variation in homicide rates or the East-West variation in suicide rates. Only the correlation between precipitation and homicide rates survived controls for latitude and longitude.

An index of the environmental thermal load imposed on exercising horses and riders by hot weather conditions.

There is a need to determine objectively the environmental heat load imposed on horses competing to an international standard in 3-day-events in environments where there is likely to be a high level of radiation added to high ambient temperatures and relative humidity; the presently used FEI 'Comfort Index' is severely limited in its applicability. It is proposed that the Wet Bulb Globe Temperature (WBGT) Index be used. This index was originally established for man exercising strenuously under harsh climatic conditions with high solar radiation levels. It may be defined as: WBGT = 0.7Twb + 0.3Tg where Twb is the wet bulb temperature of the ambient air, measured in the shade and Tg is the black globe temperature. Climatic conditions should be monitored continuously at a site representative of the detailed topography and nature of the terrain of the competition course. The upper limit for the index for competitions involving fit, fully acclimatised horses, running on ground of optimal going, is recommended to be 32.5 degrees C. This limit should be reduced, by an as yet undetermined amount, for unacclimatised and unfit horses or when the going is less good.

Microbial trace-fossil formation, biogenous, and abiotic weathering in the Antarctic cold desert.

In the Antarctic cold desert (Ross Desert), the survival of the cryptoendolithic microorganisms that colonize the near-surface layer of porous sandstone rocks depends on a precarious equilibrium of biological and geological factors. An unfavorable shift of this equilibrium results in death, and this may be followed by formation of trace fossils that preserve the characteristic iron-leaching pattern caused by microbial activity. Similar microbial trace fossil may exist in the geological record. If life ever arose on early Mars, similar processes may have occurred there and left recognizable traces.

Atmospheric sulfur: its effect on the chemical weathering of New England.

The present acidity and sulfur content of the upland streams of New England can be accounted for on the basis of the rainout and washout of sulfuric acid from the atmosphere. In spite of this excess acid flux over the New England landscape, the rate of cationic denudation of upland watersheds is relatively low.

Ecology. Weather ruins winter vacations.

There has been increasing concern over the decline in many migratory bird species. As Saether discusses in his Perspective, evidence is accumulating (Sillett et al.) that climate change resulting from the El Niño Southern Oscillation affects both the survival rate of adult birds at tropical wintering sites and their reproductive rate at summer breeding grounds in the Northern Hemisphere.

Planetary science. The weather on Titan.

When the Voyager 1 spacecraft returned images in 1980, the dense atmosphere of Saturn's moon Titan was assumed to be bland and featureless. As Lorenz discusses in his Perspective, recent ground-based spectroscopy, and images from the Hubble Space Telescope, are changing this perception. Observations such as the short-lived clouds in Titan's atmosphere reported by Griffith et al. suggest that although average precipitation is likely to be low, individual precipitation events may be heavy enough to cause deep valleys on Titan's surface.

Activity of nocturnal primates: influences of twilight zeitgebers and weather.

The time of onset of activity of bush babies (Galago senegalensis), slow lorises (Nycticebus coucang), and an owl monkey (Aotus trivirgatus) living in outdoor enclosures usually fell in certain illuminance ranges of dusk and kept pace with seasonal progressions of sunset time. Influences of cloud cover were variable, but excessive heat and cold were inhibitory. Accurate endogenous timekeeping and reliance on the most stable zeitgeber apparently maintain activities in synchrony with the rhythmically changing environment.

Association between acute glaucoma and the weather and sunspot activity.

The dates of presentation of 191 cases of acute closed-angle glaucoma which presented at the Birmingham and Midland Eye Hospital between 1971 and 1974 were analysed and the seasonal incidence of acute glaucoma confirmed (P less than 0-001). These data were compared with meteorological data for air temperature, rainfall, hours of sunshine, atmospheric pressure, cloud amount, terrestrial magnetic field level, and sunspot numbers. A statistically significant direct association (P less than 0-05) was found with hours of sunshine and an inverse association (P greater than 0-05) with cloud amount. A statistically significant inverse association (P less than 0-05) was found with sunspot count, and this assumed high significance (P less than 0-0005) on consideration of sunspot activity in the preceding period. The literature is reviewed and the significance of these findings discussed.

Marathon running and adverse weather conditions: a miscellany.

This paper considers various predisposing and corrective factors for hypothermia and hyperthermia in marathon runners. It is concluded that a race should be cancelled or deferred if the forecast suggests that certain climatic thresholds are likely to be met or crossed.
